1. BlackMagicTicketsPlugin (1) allows a permission to be specified to edit 
a ticket field.
2. ExtraPermissionsProvider (2) allow you to define new permissions.
3. A permissions policy could be implemented, similar to 
ReadonlySignedTickets (3), to deny a permission when the ticket is in a 
particular state.

Putting those three things together, I think it might work to define a new 
permission for editing the ticket description, and deny the permission when 
the ticket is in a particular state.
